Abstract

The invention relates to a solid-state laser comprising a resonator (1) with a monolithic structure consisting of a laser medium, on which a passive Q-Switch (12) and at least one resonator mirror are directly formed, and comprising several laser diodes (22) which, as pump medium, radiate into the resonator (1) from the side. A simple and robust structure which is also highly efficient is obtained, in that the monolithic resonator (1) is held at one end in a first holding plate (31) and is held at its other end in a second holding plate (32), and in that between the first and the second holding plate (31, 32) at least one carrier ring (21) is mounted which carries several laser diodes (22) which are passively wavelength stabilized.
